The following is written for programmers who don't really understand
object oriented programming yet. They probably understand the language
semantics, but don't really understand how to use them correctly.

If you find yourself misusing object oriented semantics that probably
means you don't have the skills to develop good software. This is a
problem because bad software is much harder to develop and even harder
to maintain.

Monolithic server architecture

The easiest way to support additional capacity is to simply use a bigger server (big iron approach), but the disadvantage is you need to pay for that capacity even when you're not using it, and you can't change the amount of capacity for a single server without suffering some downtime (in the traditional monolithic server architecture).

Sticking <script></script> tags referring an external resource in the middle of your HTML code will hang the loading of your page while your browser gets the missing script.

On the TurnKey website, this was a problem with the loading of the AddToAny sharing script, and the quantcast tag which I have since removed. There were also a couple of custom scripts that slowed down the site.

The solution is generic and simple. Use this code to load your Javascript asynchronously:

Having recently reread Malcolm Gladwell's excellent book: Outliers - the story of success, I've been thinking about the correlation between high IQ and success in life. I think I may have come up with a nice way to clarify Malcolm Gladwell's conclusions. Malcolm writes that to succeed in a given field you need to pass a certain threshold of intelligence, but that having more intelligence than the required threshold will not increase your chances of success.

The spam situation has recently gotten a bit out of hand and automated defenses have been giving in.

I've taken a close look at the problem and implemented a gauntlet of spam countermeasures that I'm hoping will give us back the upper hand for a while longer, without compromising on the user experience.

Previously, we only used mollom to filter out comments by anonymous users. This was easy to get around for two reasons:

A few months ago I worked a couple weeks on a new website design. Just to be clear website design isn't one of my specialties. Not be a long shot. I'm much more of an engineer at heart. That means I feel more comfortable coming up with solutions I can test objectively. Visual design doesn't fit the bill. It's more art than engineering. Open-ended. A seemingly infinite solution space. No clear fitness function that doesn't involve wishy washy, vague notions like taste and style.

If you have a website that gets a reasonable amount of traffic, you've probably considered adding advertising at one point or another. Maybe you're dreaming of quiting your day job to work full time on the site or maybe you just want to cover some basic costs.

Some people don't like the GPL3 and prefer to use the GPL2 license. We use GPL3. Just in case I missed something I just finished comparing the GPL3 to the GPL2 in detail and confirmed that we like the GPL3 better.
